This is a very high quality and correct front out put bearing. This is for the Dana 18 transfer Case. (Brown-Lipe, Dana 18, Spicer 18). This is the stock transfer case in the MB, GPW, CJ2A, CJ3A, CJ3B, M38, M38A1, and early CJ5. This is the little bearing the front four wheel drive out put shaft rides on. These are almost always worn out when found.
